(x-1)/-3 = (x+5)/6
You want to get x by itself. Start by multiplying both sides by -3 and 6:
6(x-1) = -3(x+5)
Distribute:
6x - 6 = -3x + 5
Add 6 and 3x to both sides:
6x + 3x = 5 + 6
9x = 11
Divide both sides by 9 to get x by itself:
x = 11/9
Answer:
Originally there were 30, 25 cents stamps and 20, 15 cent stamps.
Step-by-step explanation:
We are given the following in the question;
Let x be the number of 25 cents stamps and y be the number of 15 cents stamps.
Marci has a total 50 stamps.
Thus, we can write

Also,

Total cost = $16.50
Thus, we can write the equation:

Solving the two equations:

Originally,

Thus, originally there were 30, 25 cents stamps and 20, 15 cent stamps.
Answer:
200 000 + 40 000 + 6 000 + 300 + 5
5.a) Steve - 60=5×12
= <u>5×3×2×2</u>
5.b) Ian - 60=6×10
= <u>3×2×5×2.</u>
<u>Discussion</u> - The prime factors reduce to the same numbers in both Steve's and Ian's case.
5.c) Case 1 of 48 = 6×8
= <u>3×2×2×2×2.</u>
Case 2 of 48 = 12×4
= <u>2×2×3×2×2.</u>
The answer is 11 & 51/100!
